I’ve written a Ruby script that does all the things required to update your Gentoo kernel to the latest version – no need to genkernel, emerge, or grub-edit anything.
You got a new version of the Linux kernel in /usr/portage? In the future, simply type in update-kernel.rb and you’re done! Get the script here.
